This invention appertains to new and useful improvements in means for steering marine vessels, and more particularly to a novel device wherein speed crafts can be steered accurately and in an easy and convenient manner. I

Other important objects, and advantages of the invention will become apparent to the reader of the following specification.

In the drawings Figure 1 represents a' fragmentary side elevational view of a boat equipped with the novel steering means.

Fig. 2 represents a fragmentary vertical sectional view through a boat and part of the novel steering mechanism.

Fig. 3 represents a fragmentary top plan view of the steering mechanism.

Fig. at represents a fragmentary front end elevational View of the rudder.

Fig. 5 represents a sectional view through the stem of the rudder looking downwardly upon the rudder blade.

Fig. 6 represents an end elevational view of the stationary rudder.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Fig. 1 that numeral 5 represents a marine craft, and the same for the purpose of illustration is a speed boat consisting of the body construction 6 including the bottom 7.

It is the understanding, that this type of steering mechanism can be very effectively used on speed boats. In carrying out the present invention, a substantially large plate 9 is secured to the under side of the bottom 7 of the boat 6.

Upon the board 7 is secured the circumferential flange 8 of the upstanding circular cylindrical shell 8a of metal or similar mate rial having its upper end internally threaded to receive the packing gland nut 11. Interposed between the wear resisting bushing 10 and the nut 11 is the compressible packing material 12. The stem 13 extends from the rudder 1 1 upwardly through the bushing 10, packing 12 and nut 11. The upper end of this stem 13 is threaded as at 15 and reduced as at 16, and to this is secured the hand bar ment from the stem 13 by the nut on the threaded portion of the bar 19.

The ends of the bar 19 are provided with hooks 21 to which cables are attached lead- Serial No. 621,977;

ing from a suitable hand wheel adjacent the same securing elements 23 which secure the flange 8 to the floor 7 can also be adapted for securing the plate 9 to the underside of the floor 7.

It can now be seen that numeral 25 represents a stationary rudder on'the plate 9 in advance of the rudder blades 14. Obviously,

the stationary blade 25 serves to force the 7 water in advance of the blade 14 and obviously this tends materially to reduce the normal resistance of the water against the blade 14.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spiritand scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is A steering mechanism for marine crafts comprising a plate to be secured to the bottom of the craft having an opening therein and a tubular bushing extending upwardly therefrom and aligned with said opening, a rudder blade having an actuating stem projecting through the opening in the said plate and journaled in said, bushing, and a stationary depending rudder blade on the under side of said plate in advance of the firstmentioned blade.

In testimony whereof I atfix my signature.
